Abstract
The aim of the research is to establish the quantitative relationship and impacts of risks associated with various categories of occupational and workplace hazards in the Nigerian seaports. It was carried out by obtaining time series statistical data of 7 years from hazard identification and risk assessment report of Nigerian Ports Authority (NPA) Apapa, western port headquarters. The variables considered are the associated risks of various types of occupational and workplace hazards to which seaport workers were exposed from 2009-2014. The overall level of associated risks of occupational and workplace hazards represent the cumulative of various hazards and were treated as the dependent variable ‘Y’. The exposures to the risks of mechanical hazards, ergonomic hazards, physical hazards, noise/environmental hazards were symbolized as X1, X2, X3, and X4 respectively and treated as independent variables. The method of multiple regression analysis was used to analyze the time series data. T-test was used to test the hypotheses. It was found that risks associated to mechanical hazard, ergonomic hazards, noise/vibration hazard, physical hazards, all have significant impact on the overall level of risk of exposure to occupational and workplace hazards in Nigerian seaport environment. It was recommended that proactive investment in safety inspective and management system is needed to limit the level of exposure of seaport staff to occupational hazards.
